DESCRIPTION:

New Holland Tractor TN55, TN65, TN70, TN75 Service Repair Manual

GENERAL INSTRUCTIONS:

IMPORTANT NOTICE:
All maintenance and repair work described in this manual must be performed exclusively by NEW HOLLAND service technicians, in strict accordance with the instructions given and using any specific tools necessary. Anyone performing the operations described herein without strictly following the instructions is personally responsible for any eventual injury or damage to property.

BATTERY:
Before carrying out any kind of service operations, disconnect and isolate the battery negative lead, unless other- wise requested for specific operations (e.g.: operations that require the engine running). Once the specific operation has been completed, disconnect the lead in order to complete the operation.
SHIMMING:
For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up the recorder values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated for each on shim.
ROTATING SHAFT SEALS:
For correct rotating shaft seal installation, proceed as follows:
— before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes;
— thoroughly clean the shaft and check that the working surface on the shaft is not damaged;
— position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will deviate the fluid towards the inner side of the seal;
— coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip on double lip seals with grease;
— insert the seal in its seat and press down using a flat punch, do not tap the seal with a hammer or mallet;
— whilst inserting the seal, check that the it is perpendicular to the seat; once settled, make sure that it makes contact with the thrust element, if required;
— to prevent damaging the seal lip on the shaft, position a protective guard during installation operations.
O–RING SEALS:
Lubricate the O–RING seals before inserting them in the seats, this will prevent them from overturning and twist-
ing, which would jeopardise sealing efficiency.
SEALING COMPOUNDS:
Apply one of the following sealing compounds on the mating surfaces marked with an X: LOCTITE 518, LOC-TITE 5205, SUPERBOND 559 MASCHERPA or BETABLOCK A272M GURIT ESSEX.
Before applying the sealing compound, prepare the surfaces as follows:
— remove any incrustations using a metal brush;
— thoroughly de–grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a
water and soda solution.
